Its revised amplifier topology is drawn from Musical Fidelity’s TITAN power amplifier design, bringing the M5xi closer to the architecture used in the M6si and updated M6xi, but tuned for lower output power.\u003c\/p\u003e\n\u003cp\u003eThe M5xi delivers 160 W per channel into 8 ohms and 240 W per channel into 4 ohms, with 45 amps peak-to-peak current and enough headroom to drive demanding loudspeakers with control. Its low-distortion Darlington output stage is arranged in classic Musical Fidelity fashion, while the PCB layout is designed to reduce circuit imbalances that would otherwise require corrective feedback.\u003c\/p\u003e\n\u003cp\u003eConnectivity has been substantially updated, with HDMI eARC, coaxial, optical, and USB-C digital inputs, plus 4 line-level RCA inputs and an upgraded MM\/MC phonostage. A home-theater bypass input allows the M5xi to serve as the front left\/right amplifier in a multichannel system, while fixed line outputs and variable preamp outputs support headphone amplifiers, bi-amping, or active subwoofer integration.\u003c\/p\u003e\n\u003ch4\u003eFully Discrete Power Amplifier\u003c\/h4\u003e\n\u003cp\u003eThe M5xi is configured as 2 independent monobloc power amplifiers with a separate preamp stage, effectively combining a preamp and 2 power amps in one chassis. The amplifier stage uses Musical Fidelity’s classic low-distortion output topology and incorporates technology from the company’s TITAN amplifier platform.\u003c\/p\u003e\n\u003cp\u003ePower delivery is central to the design. The M5xi provides 160 Wpc into 8 ohms, 240 Wpc into 4 ohms, and 45 amps peak-to-peak current, giving it the headroom and control needed for difficult speaker loads and low-impedance dips.\u003c\/p\u003e\n\u003ch4\u003eModern Inputs and System Integration\u003c\/h4\u003e\n\u003cp\u003eThe M5xi adds HDMI eARC for TV and home-theater use, along with coaxial, optical, and USB-C digital inputs supporting up to 24 bit\/192 kHz resolution. RS232 control allows integration into custom-installed systems, and a 5 V\/2 A USB-A power output provides a clean power source for compatible external streamers.\u003c\/p\u003e\n\u003cp\u003eThe home-theater bypass input bypasses the preamp stage, allowing the M5xi to operate as a high-performance stereo power amplifier for the front left and right channels in a multichannel system. Fixed line outputs and variable preamp outputs provide additional flexibility for headphone amplifiers, external power amps, or active subwoofers.\u003c\/p\u003e\n\u003ch4\u003ePhonostage and Digital Separation\u003c\/h4\u003e\n\u003cp\u003eThe built-in MM\/MC phonostage has been redesigned from the M5si’s MM-only stage, adding moving-coil cartridge support along with improved circuit design, layout, isolation, and shielding. The transformer and power supply PCB are encapsulated in a metal enclosure to reduce electromagnetic interference throughout the amplifier, with particular benefit to the high-gain phonostage circuitry.\u003c\/p\u003e\n\u003cp\u003eDigital and analog sections are physically separated on dedicated PCBs, with the digital and ARC boards using their own linear power supply. This separation is designed to reduce RF interference and protect the sensitive analog signal path.\u003c\/p\u003e\n\u003ch4\u003eBuild Quality\u003c\/h4\u003e\n\u003cp\u003eThe M5xi’s front panel is milled from a massive extruded aluminum profile, with a metal case designed to provide mechanical rigidity and electromagnetic shielding. The casework helps reduce the effects of vibration while also protecting the amplifier’s internal circuits from external electromagnetic interference.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003ePower Output (8 ohm, 4 ohm):\u003c\/strong\u003e 160 W, 240 W\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eContinuous Power (8 ohm, 4 ohm, 20 Hz–20 kHz, 0.09% THD):\u003c\/strong\u003e 140 W, 210 W\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePeak Power (8 ohm, 4 ohm):\u003c\/strong\u003e 190 W, 320 W\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Voltage:\u003c\/strong\u003e 36 V RMS, 20 Hz–20 kHz at onset of clipping\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePeak-to-Peak Voltage:\u003c\/strong\u003e 101 V\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePeak-to-Peak Current:\u003c\/strong\u003e 45 A\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDamping Factor:\u003c\/strong\u003e 47 into 8 ohms\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Devices:\u003c\/strong\u003e 2 pairs per channel\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLine Input THD+N:\u003c\/strong\u003e \u0026lt;0.009% typical, 20 Hz–20 kHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSignal-to-Noise Ratio:\u003c\/strong\u003e \u0026gt;105 dB, A-weighted\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLine Input Impedance:\u003c\/strong\u003e 40 kΩ\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e +0, –0.1 dB, 10 Hz–20 kHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAnalog Inputs:\u003c\/strong\u003e 4 x stereo RCA line-level, 1 x MM\/MC phono\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDigital Inputs:\u003c\/strong\u003e 1 x HDMI eARC, 1 x coaxial, 1 x optical, 1 x USB-C, up to 24 bit\/192 kHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAnalog Outputs:\u003c\/strong\u003e 1 x stereo RCA fixed line output, 1 x stereo RCA preamp output\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpeaker Outputs:\u003c\/strong\u003e 2 pairs 4 mm banana plugs\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eControl:\u003c\/strong\u003e RS232 D-sub connector, trigger input and output\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUSB Power Output:\u003c\/strong\u003e 5 V\/2 A USB-A\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhono Sensitivity (MM, MC):\u003c\/strong\u003e 3 mV, 0.4 mV\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhono Gain (MM, MC):\u003c\/strong\u003e 40 dB, 60 dB\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhono Signal-to-Noise Ratio:\u003c\/strong\u003e \u0026gt;87 dB, A-weighted\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhono Input Capacitance:\u003c\/strong\u003e 220 pF\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhono Input Impedance (MM, MC):\u003c\/strong\u003e 50 kΩ, 1 kΩ\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhono Frequency Response:\u003c\/strong\u003e RIAA\/IEC ±0.4 dB, 20 Hz–20 kHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Requirement:\u003c\/strong\u003e 115\/230 V AC, 50\/60 Hz, factory pre-set\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Consumption:\u003c\/strong\u003e 320 W maximum\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions (WHD):\u003c\/strong\u003e 17.3\" x 4.9\" x 15.9\" (440 x 125 x 405 mm)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 33.1 lb.
